BRICK AND BLOCK MOLD.

Specification o' Letters Patent.

Patented .Tune 22, 1909.'

Application led August "l, 1908. Serial No. 47,438.

To all whom it may concern:

Be it known that I, CHARLES W. JONES, a citizen of the United States,residing at Charlotte, in the county of lw/lccklenburg and State ofNorth Carolina, have invented a new and useful Brick and Block Mold, ofwhich the following is a specification.

This invention relates to molds for making artificial stone bricks orblocks of that general class shown and described in United StatesLetters Patent issued to me on the 12th day of May 1908 under No.887,398.

The object of the invention is to improve and simplify the constructionof the mold and to so arrange the core members as to permit removal ofthe same from the top of the mold, thereby leaving the bricks or blocksresting closed end down on the pallet.

A further object of the invention is to provide a mold having a coreformed of a plurality of sections separated by division plates to formindependent molding compartments.

A further object is to provide means for clamping the core members inengagement with the division plates, and means for releasing said platesthereby to permit removal of the molded product.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to Within the scope of theappended claims.

In the accompanying drawings forming a part of this specification:Figure 1 is a perspective view of a brick or block mold constructed inaccordance with my invention, a portion of the side walls and divisionplates being broken away to more clearly show the construction of thesame. Fig. 2 is a detail longitudinal sectional view. Fig. 3 is a topplan view of a portion of the mold' showing the spacing members inclosed or operative position. Fig. f1 is a similar view showing thespacing members in extended or operative position. Fig. 5 is atransverse sectional view. Fig. 6 is a detail perspective view of one ofthe spacing members detached. Fig. 7 is a detail perspective view of aportion of the brick facing plate.

Similar numerals of reference indicate corresponding parts in all of thei'igures of the drawings.

The improved mold forming the subject 'matter of the present inventionincludes a pallet 5 on which are mounted vertically disposed end pieces6 having transverse slots 7 formed therein and spaced from the lowerlongitudinal edges of the end pieces, as shown.

interposed between the end pieces 6 is a core member formed of aplurality of separate sections 9 each preferably stamped or otherwiseformed from a single sheet of metal having its opposite ends bent toproduce terminal beads 10 adapted to receive a connecting rod or wire11. The opposite edges of the core sections 9 are cut away to produceshoulders 12 which bear against corresponding shoulders 13 'formed inthe division plates 1K1. The division plates 14 are spaced apart by thecore sections 9 to form independent molding compartments 15 conformingto the shape of the core sections, tllierleby to produce a substantiallyU shaped b oc i.

A pair of division plates 14 are arranged at the juncture of adjacentcore sections and interposed between said plate are co-acting wedgeshaped spacing members 16 preferably extending the entire height of theplates lli and having their lower edges resting on the pallet 5. Eachspacing member or block 16 is provided with a vertical extension 17adapted to bear against the exterior walls of the adjacent coresections, said spacing members being formedV withV longitudinallydisposed slots 1S arranged in horizontal alinement with each other andeach having one wall thereof formed with a series of teeth constitutinga rack 19.

Disposed longitudinally of the mold and extending through the severalcore sections are spaced longitudinally movable actuating rods 20 havingo enings formed therein for the reception of camping pins 21, whichlatter are arranged to bear against the adjacent division plates 14 forthe purpose hereinafter referred to.

Slidably mounted between the actuating rods 2O is an auxiliary actuatingrod 22 also provided with vertically disposed pins 23 similar inconstruction to the pins 21.

The clamping pins or members 21 of the actuating rods 20 are arranged tobear against one of the division plates of each -k from the forward formsupports for loclring devices 311-.

set, while the pins 23 oi' the auxiliary actuating rod 23 are arrangedto bear against the mating plate of said set, thereby to clamp saiddivision plates in engagement with said spacing blocks and l thussupport the core members and their associated parts in assembledposition during the molding operation.

The actuating rods are formed with gear teeth 24 which engage the teethof the racks 19 and serve to move the spacing blocks to operative andinoperative positions when said actuating rods are rotated, there beinghand operated levers 25 depending` ends of the actuating rods 20 forrotating said rods to ei'lect the movement of' the wedge shaped spacingblocks.

Pivotally mounted at 26 on the forward end of the auxiliary actuatingrod 22 is a pair oi levers 27 having their intermediate portionsextended between spaced collars 28 on the actuating rods 20 andpivotally mounted at 29 on said rods, as shown. The free ends of thelevers 27 are extended longitudinally beyond the pivot points 29 so thatby moving the free ends of the levers 27 in the direction of the arrowindicated in Fig. 1 of the drawings, the actuating rods 2O will be movedlongitudinally of the mold in the direction of the front end thereof soas to release the pins 21 from engagement with the adjacent spacingplates, while the central or auxiliary rod 22 will be moved in theopposite direction so as to move the clamping pins 23 out of engagementwith the mating division plates. When the levers 27 are moved in thedirection of the rear end of the mold the clamping pins on the main andauxiliary actuating rods 2O and 22 will be moved toward each other thusbringing the mating plates ot' each set together so as to separate thesame from the cement or concrete constituting the body of the block andthus permit the ready removal of the latter.

rlhe intermediate portions of the division plates are formed withsuitable openings for the reception oi the main and auxiliary actuatingrods, while the upper edges thereof are provided with vertical recesses30 so as to permit the core sections to be readily posi tioned in themold with the shoulders 12 bearing against the shoulders 13 on saiddivision plates.

Extending transversely across the main and auxiliary actuating rods is abar 31 having a depending pin 32 wl'iich travels in an elongated slot 33i'ormed in the central rod 22, the opposite ends of the bar 31 beingconnected with the actuating rods 20 and extended longitudinally beyondsaid rods to The locking devices 34 are preferably in the form of levershavin@` their intermediate portions pivotally mounted at 35 on theextended ends of the bar 81 and their inner ends provided with cam faces36 adapted to bear against the adjacent end pieces 6 for clamping thecore sections and division plates in assembled position.

Extending longitudinally of the mold and bearing against the oppositeends of the division plates 14 are side strips 37 which engage the endpieces 6 and constitute the side walls of the molding compartments.

ln operation the hand cranks 25 are rotated so as to cause the gears onthe actuating rods to engage the racks on the spacing plates and movethe latter to operative posi tion between the division plates. Thelevers 27 are then moved toward the rear of the mold which causes theclamping pins on the main and auxiliary rods to engage the adjacentdivision plates and clamp the latter in engagement with the spacingmembers. The locking members 34 are then actuated to clamp the divisionplates and core members in assembled position, after which the cement,concrete or other plastic material is introduced Within the moldingcompartments 15. After the cement in the molding` compartments has setthe locking members or cams 31 are moved to released position and thecranks 25 rotated to Withdraw the spacing members 16 from between thediviA sion plates, after which the levers 27 are moved toward the rearend oi the mold which presses the division plates together and thusprevents the same from adhering to the cement constituting the body oithe block. TWhen the division plates have been drawn together the moldis lifted bodily from the pallet thus leaving the molded bricks orblocks resting closed end down on said pallet and in which position theymay be readily carried to the drying racks without danger of breakage.

lin order to form the briclfis or blocks with an ornamental or 'linishedsurface there is pro vided a plurality of longitudinally adjustableplates 39 arranged in over-lapped relation and provided with dependingextensions 40 adapted to lit between the walls of the adj acent moldingcompartment 15, the sets of over-lapped plates being spaced apart toform an auxiliary compartment 41 for the reception oi relatively finematerial constituting the exposed face of the bloclr. The upper edges ofthe plates 39 are provided with laterally extending wings d2 whichconstitute in effect a hopper and serve to direct the material into theauxiliary compartment 41.

ln using the facing attachment shown in Fig. 7 the extensions l0 areintroduced within the compartments and said extensions adjustedlongitudinally so as to close the outer ends of the main moldingcompartment and produce the auxiliary molding compartment 41, saidextensions being fastened in adjusted position by a loclring member 42.One end of the locking member 42 is pivotally mounted on one of theplates 39, while the opposite end thereof is provided with a series ofnotches 43 adapted to engage a pin 44 extending laterally from theadjacent plate 39. lll/*hen the facing attachment is fastened inposition in the manner descr'ibed, the main compartment is iilled withrelatively coarse material, while the auxiliary compartment is lilledwith 'Ene sand and cement so as to give the exterior tace of the block aneat finished appearance.

lt will here be noted that by moving the spacing members 16 laterallyand inserting longer division plates the capacity of the moldingcompartments may be varied so as to permit the formation of bricks orblocks ot dil'l'erent sizes.

A suitable dellector l5 is arranged above the several core sections fordetlecting the cement or concrete into the molding compartments.

The molds may be made in different sizes and shapes and several of saidmolds arranged side by side, in which. event, each set ol molds will beprovided with a dei'lector for directing the material into the adjacentcompartments.
